NSUbiquityIdentityDidChangeNotification doesn't work?

Question

I\'m creating a cloudkit app, and have been trying multiple ways to get the NSUbiquityIdentityDidChangeNotification, but I never am able to get this notification.

Answer 1

To be notified in iOS when a user logs in or out of iCloud while using your app, use CKAccountChangedNotification instead of NSUbiquityIdentityChanged notification.
